Potential Economic And Environmental Impacts Of Alternative Sediment Control Policies, Center For Agricultural And Rural Development, Iowa State University, Joseph C. Campbell Dec 1979

Potential Economic And Environmental Impacts Of Alternative Sediment Control Policies, Center For Agricultural And Rural Development, Iowa State University, Joseph C. Campbell

CARD Reports

This study focuses on the interaction of U.S. agricultural exports, regional patterns of farm production, and the problem of agricultural sediment. It also evaluates alternative policies in abating sedimentation of the nation's main river basins. One underlying hypothesis of the study is that changes in agricultural export demands cause shifts in the comparative advantage among producing regions within the United States and alter regional land use patterns, farm incomes, consumer food prices, and soil loss. Given this hypothesis, the study uses a mathematical model and two estimates of the U.S. 1985 agricultural exports to investigate if and ...


Mechanism Of Decarboxylation Of Glycine And Glycolate By Isolated Soybean Cells, David J. Oliver Dec 1979

Mechanism Of Decarboxylation Of Glycine And Glycolate By Isolated Soybean Cells, David J. Oliver

David J. Oliver

Isolated soybean leaf mesophyll cells decarboxylated exogenously added [1-14C]glycolate and [1-14C]glycine in the dark. The rate of CO2 release from glycine was inhibited over 90% by isonicotinic acid hydrazide and about 80% by KCN, two inhibitors of the glycine to serine plus CO2 reaction. The release of CO2 from glycolate was inhibited by less than 50% under the same conditions. This indicates that about 50% of the CO2 released from glycolate occurred at a site other than the glycine to serine reaction. The sensitivity of this alternative site of CO2 release to an inhibitor of glycolate oxidase (methyl-2-hydroxy-3-butynoate ...

Electronic Structure Of Nb-Mo Alloys, E. Colavita, A. Franciosi, R. Rosei, F. Sacchetti, E. S. Giuliano, R. Ruggeri, David W. Lynch

Physics and Astronomy Publications

Thermoreflectance measurements on NbxMo1−x alloys (x=0.2, 0.5, 0.8) have been carried out in the 0.5-5.0 eV energy region. Augmented-plane-wave (APW) calculations for Nb at two different lattice parameters and for Mo, as well as coherent-potential-approximation calculations (CPA), have been carried out and have been used in the interpretation of the experimental results. Several optical transitions [Σ1(EF)→Σ3, G4(EF)→G1,N2→N′1], have been identified, and their concentration dependence followed. These results contribute significantly toward putting the interpretation of the optical properties of Nb, Mo, and their alloys on a much ...


Intergenerational Transfers And Estate Planning: The Iowa Experience, Michael Boehlje, William Good, Neil E. Harl, John Achterhof Nov 1979

Intergenerational Transfers And Estate Planning: The Iowa Experience, Michael Boehlje, William Good, Neil E. Harl, John Achterhof

Special Report

With high rates of inflation, the rapid growth in estate size (particularly for estates that include real property), and thus concerns about the increased cost and complexity of intergenerational transfers of property, more information is being requested by estate owners and their advisors (accountants, attorneys, lenders, life insurance representatives, extension economists, and others) on the various methods and procedures that might be used in estate planning. Furthermore, recent changes in both federal estate and Iowa inheritance tax laws suggest that estate plans should be reviewed carefully to determine whether they are consistent with changes in tax regulations as well as ...

Response Functions For Nontraditional Inputs In Agriculture, Michael D. Boehlje, Donald Collins, Jeffrey Apland

ISU Economic Report Series

As part of the restructured regional research program of the U.S. Department of Agriculture and the Land-Grant Universities, a research strategy committee (NCR-113) was formed in 1978 to identify new research tHrusts in the area of farm firm management-and finance. At the .first meeting in April, 1979, a number of possible areas for additional research activity or new thrusts were identified. One area identified was that of the development and utilization of "new" inputs in agri culture and the estimation of response functions for these inputs...


Don Kaldor Memorial Lecture "Concepts Of Entrepreneurship And Agricultural Research", T. W. Schultz Oct 1979

Don Kaldor Memorial Lecture "Concepts Of Entrepreneurship And Agricultural Research", T. W. Schultz

Economic Staff Paper Series

I BEGIN WITH THREE INNOCENT QUESTIONS. WHO ARE THE ENTREPRENEURS IN OUR SOCIETY? WHAT DO THEY DO AS ENTREPRENEURS? What is the economic value of the function they perform? On the first question, entrepreneurship is a pervasive activity because of the social and economic dynamics that characterizes our society and because no one—not even ivory tower professors OR institutionalized priests—can escape the on-going dynamics. ACCOMMODATIONS and adjustments are the order of the DAY/ AND these entail entrepreneurship.

Applications Of Economics In Plant And Animal Breeding, Bryan E. Melton Oct 1979

Applications Of Economics In Plant And Animal Breeding, Bryan E. Melton

Economic Staff Paper Series

Throughout history man's very existence has been characterized by his continuing struggle to obtain sufficient food, clothing and shelter. With a growing population and declining agricultural resources such as energy, water and land, the greatest challenge to fulfilling these fundamental human needs may be yet to come. One means of meeting growing demands on an agriculture faced with shrinking resource availability is by improving the productivity of the plant and animal species used in agriculture. Breeders attempt to achieve this improvement through the application of the principles of modern quantitative genetics to the breeding of plants and animals for ...


An Analysis Of American Agriculture Under Various Policy Alternatives For 1980, Center For Agricultural And Rural Development, Iowa State University, Ashok Chowdhury, Earl O. Heady Oct 1979

An Analysis Of American Agriculture Under Various Policy Alternatives For 1980, Center For Agricultural And Rural Development, Iowa State University, Ashok Chowdhury, Earl O. Heady

CARD Reports

Historically, the U.S. farm sector has been a leader in meeting the challenges of the world's growing food demand. American farmers produced an impressive 24 percent of the total world food and feed grains in 1977. They also contributed 53.6 percent of total world exports of these farm commodities in the same year. This achievement was possible through a combination of past governmental policies and technological developments. In the beginning cheap land and other inexpensive inputs encouraged farmers to increase agricultural production by expanding the use of these inputs. Gradually, technological innovations and mechanization of agriculture accelerated ...

Factor-Market Distortions And Dynamic Optimal Intervention: Reply, Harvey E. Lapan Sep 1979

Factor-Market Distortions And Dynamic Optimal Intervention: Reply, Harvey E. Lapan

Economics Publications

Edward Ray, in his comment on my 1976 paper, analyzes a slightly different model than the one I presented, and thus reaches different conclusions. His principal conclusions are that: (i) given wage rigidities, a wage subsidy to producers is needed, and this subsidy is equivalent to the optimal static subsidy that ensures full employment in each sector; and (ii) given the forced equilization of wages across sectors, a subsidy to workers is needed to encourage labor transfers between sectors. Thus, Ray finds that full employment is always desirable, whereas I find that some unemployment is (usually) present along the optimum ...


An Economic Analysis Of Expenditures On State Experiment Station Research, Wallace E. Huffman, John A. Miranowski Aug 1979

An Economic Analysis Of Expenditures On State Experiment Station Research, Wallace E. Huffman, John A. Miranowski

Economic Staff Paper Series

The last decade can be characterized by a growing skepticism of the agricultural research establishment. Some have argued that agricultural researchers have been captured by the interests of large farmers or by large private farm input supply firms. Others have argued that the agricultural research establishment has been unresponsive to human resource, environmental, and income distributional issues. Some of these concerns have been expressed in recent changes made in the type of federal support for agricultural research.

Agriculture And Water Quality Improvement, Lee A. Christensen, John A. Miranowski Jul 1979

Agriculture And Water Quality Improvement, Lee A. Christensen, John A. Miranowski

ISU Economic Report Series

The symposium "Agricultural and Water Quality Improvements; What are the Implementation Costs and Policy Issues?" was organized to establish what is known and to identify additional research needs. The major impetus for action on agricultural nonpoint source pollution problems comes from Section 208 of the Federal Water Pollution Control Amendments of 1972 and the Rural Clean Water Program. Public programs involving large expenditures from both public and private sources are being implemented and require economic research and analysis...


Stability, Random Disturbances, And The Exchange Rate Regime, Walter Enders, Harvey E. Lapan Jul 1979

Stability, Random Disturbances, And The Exchange Rate Regime, Walter Enders, Harvey E. Lapan

Economic Staff Paper Series

Economists have long debated the relative merits of fixed versus flexible exchange rate systems. One of the major issues in this debate concerns the ability of the exchange rate system to isolate a nation from external disturbances: see for example, papers by Mundell (1960), Stern (1963), Tower and Courtney (1974), and Enders (1977), Fischer , (1977) added another dimension to the controversy by examining the relative stability of real consumption and prices, assuming that the economy is subject to stochastic disturbances. His principle conclusion for the small open economy is that if disturbances are . external, then a flexible exchange rate regime ...

Social Security Taxation And Intergenerational Risk Sharing, Walter Enders, Harvey E. Lapan Jul 1979

Social Security Taxation And Intergenerational Risk Sharing, Walter Enders, Harvey E. Lapan

Economic Staff Paper Series

The life cycle hypothesis has become the dominant mode used to analyze the effects of a social security system on private saving, the labor/leisure choice, and social welfare. As both Barro and Samuelson indicate, a fully funded Social Security program (in a world of certainty) would drive out an equivalent amount of private saving. If the interest rate is r, the effects of a payment of a dollar into the social security pool while young would just offset* the effects of receiving (1+r) dollars as a transfer when retired. Papers by Diamond, Hi», and Samuelson, among others, have ...

Chemistry Publications

A general procedure is described where an aryllithium, generated by metalation of a protected phenol with n-butyllithium, adds in a conjugate manner to diethyl ethoxymethylenemalonate to give after acid hydrolysis an oxygenated 3-carbethoxycoumarin. By this procedure the ethyl vinyl ethers 9, 11, 13, and 15 are converted into the corresponding coumarins 10, 12, 14, and 16 in a single reaction vessel in good yield.


Puerto Rican Consumption Expenditure Patterns In Services: A Review And Re-Examination, Richard Weisskoff Jun 1979

Puerto Rican Consumption Expenditure Patterns In Services: A Review And Re-Examination, Richard Weisskoff

Economic Staff Paper Series

This paper opens by examining the recent record of economic growth in Puerto Rico, changes in structure of output and employment and the gross flows to and from the Island—in both financial and human terms. We then review the record of personal consumption expenditures in Puerto Rico through time series of national accounts and a comparison of budget studies administered in 1941, 1953 and 1963. The 1963 survey is analyzed in more detail using multivariate functions and many socioeconomic and demographic variables. The results are then compared with other developing countries. Finally, the distribution of consumption is examined by ...

The Arrow-Lind Theorem In A Continuum Economy, Roy Gardner

Economic Staff Paper Series

In their stimulating contribution to the theory of cost-benefit analysis, Arrow and Lind showed that "when the risks associated with a public investment are publicly borne, the total cost of risk bearing is insignificant and, therefore, the government should ignore uncertainty in evaluating public investments... This result is obtained not because the government is able to pool investments but because the government distributes the risk associated with any investment among a large number of people. It is the risk-spreading aspect of government investment that is essential to this result." Arrow and Lind proved their result from an asymptotic point of ...
